FIG.9

RI) @[ECJCD FBGJI POCKET HAND STAMP BACKGROUND OF THE INVENTION Thisinvention relates to a pocket hand stamp and more particularly to apocket hand stamp in which the printing plate can be covered to preventthe ink on the printing plate from contaminating other objects and whenthe stamp is to be used a handle for the stamp is provided by openingthe covers.

Pocket hand stamps of such type so far known have been disadvantageousin that they are-complicated in structure and unstable when in use.

SUMMARY OF THE INVENTION It is therefore an object of the presentinvention to provide a pocket hand stamp of the type mentioned which issimple in structure and stable when being used.

Other objects of the invention will be apparent from the detaileddescription of the preferred embodiments given hereinafter.

The pocket hand stamp in accordance with the invention comprises aholder holding a printing plate on its bottom and-a pair of box-shapedcovers pivoted to the upper portion of the holder, in which said coversserve to cover the printing plate when they are turned to a positionunder the holder and serve to provide a handle for, the stamp when theyare turned to another position over the holder where they are placedupright back to back.

Also in accordance with the invention, in the above mentioned pockethand stamp, the holder has a detachable cover plate on its top, saidholder and cover plate have each a pair of recesses to form bearingholes, in mutual cooperation, atthe outer sides of both ends, and eachof said box-shaped covers has pivots at the inner sides of both ends toengage with said bearing holes.

Also in accordance with the invention, in the above FIG. is a splitperspective view of the pocket hand stamp shown in FIG. 1,

FIG. 3 is a front view, partially in cross-section, of the pocket handstamp shown in FIG. 1,

FIG. 4 is a front view, partially in cross-section, of the pocket handstamp as shown in FIG. 2,

DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION In the first embodimentshown in FIGS. 1 to 5, a holder 1 is of a shape-of a box with an opentop 2 and an open bottom 3 and is preferable made of acrylic bu.-tadiene styrene copolymer resin. The bottom 3 has a inner flange 4 andthe top 2 has a pair of recesses 5 at the outer side of each end.

A printing plate 6 has a printing surface 7 on its one side and ispreferably made of an elastic sponge material having numerous finecontinuous forms eLg. of nitryl butadiene copolymer rubber. The mostsuitable method for manufacturing this porous material includes theapplicants US. Pat. No. 3,342,91 l (corresponding patents German1,301,473, French 1,488,216, Italian 760,731, Japanese 448,019),

The printing plate 6 is supported on the flange 4 so that its printingsurface 7 extends outward beyond the flange 4. An ink pad 8 ispositioned on the printing plate 6 in the holder 1. The ink pad 8 ispreferably made of a porous material of polyvinyl formal resin or felt.Therefore by impregnating the printing plate 6 and the ink pad with inkin advance, continuous stamping is possible without using a separatestamp pad.

A cover plate 9 is tray-shaped and detachably mounted on the open top 2.The cover plate has a pair of recesses 10 at the outer side of each end.Each of the recesses 10 is to be combined with each recess 5 of theholder 1 to form a bearing hole.

An indicating plate 11 anda transparent plate 12 are overlaid within thecover plate 9, the projections 13 on both ends of the transparent plates12 being removably fitted in holes 14 at the ends of the cover plate 9.

A pair of box-shaped covers 15, preferably made of polyacetal resin,have each of them pivots 16 on the inner sidesof both ends to engage thebearing holes formed by said recesses 5, 10. The box-shaped covers 15may be pivotally affixed to the holder 1 by fitting the pivots 16 intothe recesses 5 and then fitting the cover plate 9 on the open top 2 ofthe holder 1.

The boxshaped cover 15 has a pair of snap members 17 for opening orclosing at its flange, and has ribs 18 in the inside for reinforcementand non-slippage when holding.

The box-shaped covers 15 cover the printing plate 6 when they are turnedto the position under the bottom side 3 of the holder 1 (see FIGS. 1 and3), and provide a handle for the stamp when they are turned totheposition over the top 2 of the holder 1 and are placed upright backto back. (see FIGS. 2 and 4).

When the covers are placed to cover the printing plate'6, inner edges 19of the snap members 17 engage each other to maintain the box-shapedcovers 15 in respect to the covers 15, thus making it possible to usethe stamp in a stable manner.

When the ink is to be replenished, the cover plate 9 is removed from theholder 1 and some ink is dropped from .the top opening of the holder 1and is dispersed in the ink pad 8, whereby the ink gradually reaches theprinting plate 6 so as again to perform clear and continuous stampingwithout using a separate stamp pad.

The pocket hand stamp of the invention uses a relatively small number ofcomponent parts and therefore a relatively small quantity of materials.

If such plastic material as mentioned before is used, the hand stampbecomes lighter and more pocketable.

In the flange 4 at both ends of the holder 1 are provided recesses 20for communication of air between the inside and the outside of theholder 1.

- In the second embodiment shown in FIGS. 6 to 8, a

holder 21 is of box shape and has a tray-shaped top plate 22 and an openbottom 23. The tray-shaped top plate 22 has lattice-shaped ribs 24 inits inside. An indicating plate 25 and a transparent plate 26 aresuperposed within the tray-shaped top plate 25. Projections 27 formed atthe ends of the transparent plate 26'are removably fitted in holes 28provided at the ends of the tray-shaped top plate 22.

An ink pad 29 and a printing plate 30 are superposed in the holder 21. Ametallic frame 31 is fitted at the open bottom 23 of the holder 1between the peripheral edge of the printing plate 30 and the innersurface of a side wall 32 of the holder 21, whereby the printing plate30 is supported by the holder 21 and a printing surface 33 of theprinting plate 30 extends outward beyond the metallic frame 31.

The holder 21 has a pair of bearing holes 34 in the outer portion ofeach top end. Longitudinal grooves 35 are provided along the outersurface of the side wall 32 of the holder 21 and extend from the bearingholes 34 to the bottom 23.

A pair of box-shaped covers 36 has pivots 37 at the inner sides of theirends to engage said bearing holes 34.

The box-shaped covers 36 may be pivotally secured to the holder 1 bymaking'the pivots 37 go via the longitudinal grooves 35 into the bearingholes 34 by using the elasticity of the box shaped covers 36.

The box-shaped covers 36 have snap members 38 in their flange foropening or closing and has ribs 39 in their interior for reinforcementand slipage-prevention when holding.

. The cover plate 9 in the embodiment shown in FIG.

'1 may be of a shape having an ink replenishing hole a as shown in FIGS.9, 10, ll, 12 in order to the-easily replenish the ink. In this case,the covers 15 can not be removed without removing cover plate 9 from theholder 1. Thus, after having removed the transparent plate 12, theindicating plate 11 and a plug 12 ink is dropped through the inkreplenishing hole a and absorbed in the ink pad 8 whence its invades theprinting plate 6 and reaches the printing surface 7. Therefore it ispossible to perform clear stamping for a long period of time. i
